The industrial sugar cane must be processed free of impurities, whether they are vegetal or mineral (dirt), and for this, the traditional process guides the washing of this sugar cane, before the milling.

Although efficient, this technique contributes for a bigger use of water. In the direction of little intervening with the environment, and to better conserve it, Group Farias has been developing the Project Clean Sugar Cane, to bring to the production areas the raw material free of impurities.

The goal is to work with vegetal impurity below 5% and mineral impurity below 1%. In this direction, the Project has been training, since 2004, the involved staff in the harvest and transport of the sugar cane, in order to allow the suspension of the activity of " washing of the sugar cane" in 70% of the crop
